Description

Technical Field

[0001] The utility model relates to the technical field of square tube galvanizing splash and oxidation prevention, in particular to a square tube hot-dip galvanizing splash and oxidation prevention device. Background Art

[0002] Hot-dip galvanizing is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, they are cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

[0003] In the prior art, during the galvanizing process of square rectangular tubes, when the square rectangular tubes are placed in a zinc pool, zinc liquid will splash out, causing danger to the workers, and when the zinc liquid leaves the zinc pot, oxidation will be accelerated, resulting in a waste of zinc. In addition, the existing galvanizing splash-proof devices mostly use motors, electric push rods, etc. to drive the cover plate to prevent splashing, which increases the cost. Utility Model Content

[0011] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0012] Through the coordinated arrangement of the hinge block and the top plate, when the square tube slides from the conveying platform to the hinge block, the gravity of the square tube can drive the hinge block to deviate, so that the two hinge blocks that are arranged opposite to each other and deviate drive the top plate to move downward through the double-head telescopic rod, so that the top of the frame is closed by the hinge block and the top plate to prevent zinc liquid from splashing and thus oxidation;

[0013] Through the coordinated setting of the spring and the double-headed telescopic rod, the hinge block can drive the top to move down and close through the double-headed telescopic rod to prevent splashing. The spring drives the top plate and the hinge block to slowly reset, which saves costs compared to driving by a motor or an electric push rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] See also Figures 1 to 3The embodiment of the present application provides a square tube hot-dip galvanizing anti-splash and anti-oxidation device, including a frame 1, a conveying platform 2 is installed on both sides of the frame 1, the upper surface of the conveying platform 2 is smoothly set, the output end of the conveying platform 2 is hinged with a hinge block 3, the upper surface of the hinge block 3 is flush with the conveying platform 2, two arc-shaped slots 4 are provided on the frame 1, a connecting block 5 is installed at one end of the hinge block 3, the connecting block 5 is slidably engaged in the arc-shaped slot 4, a vertical slot 6 is provided on the frame 1, the vertical slot 6 is narrow at the top and wide at the bottom, the vertical slot 6 is connected with the arc-shaped slot 4, a top plate 7 is slidably engaged in the vertical slot 6, a double-headed telescopic rod 8 is installed at the bottom of the top plate 7, the output end of the double-headed telescopic rod 8 is connected to the connecting block 5, a spring 9 is installed in the vertical slot 6, a flexible block 10 is installed at the bottom of the spring 9, the flexible block 10 can be a rubber block, and the flexible block 10 is connected to the top plate 7.

[0020] In this embodiment, the square tube slides from the smooth upper surface of the conveying platform 2 to the hinge block 3; the square tube should be placed horizontally so that when the square tube slides onto the hinge block 3, the entire square tube is located on the hinge block 3; at this time, the gravity of the square tube itself causes the hinged hinge block 3 to deviate and rotate, thereby sending the square tube into the frame 1. When the hinge block 3 rotates, the connecting block 5 sliding in the arc-shaped slot 4 is driven to rotate together. While the two connecting blocks 5 compress the double-headed telescopic rod 8, they drive it to slide downward. The sliding double-headed telescopic rod 8 drives the top plate 7 to slide downward in the vertical slot 6. The hinge block 3 can form a closed space with the top plate 7 on the top of the frame 1, so that the zinc liquid is not easy to splash out; when the square tube drives the hinge block 3 to rotate to a certain angle , the square tube will break away from the hinge block 3 and fall into the zinc liquid pool of the frame 1, and the hinge block 3 will have a certain rotational inertia to continue to close the top of the frame 1; the hinge block 3 can close the top of the frame 1 with the top plate 7, thereby achieving the purpose of splash and oxidation prevention, and the vertical slot 6 is narrow at the top and wide at the bottom, so that when the spring 8 is stretched, the flexible block 10 connected to the bottom of the spring 8 can move down normally, and when the spring 8 is stretched and reset by the top plate 7, the flexible block 10 cooperates with the vertical slot 6 to slow down the rebound speed of the spring 8, thereby lengthening the closing time of the top plate 7 and the hinge block 3 to the top of the frame 1, and when the spring 8 drives the top plate 7 to reset, the connecting block 5 connected by the double-headed telescopic rod 8 drives the hinge block 3 to reset together, so as to facilitate the next galvanizing.

[0021] In some embodiments, in order to allow the zinc liquid splashed onto the top 7 to fall down in time, a triangular plate 11 is installed at the bottom of the top plate 7 .

[0022] In some embodiments, in order to facilitate the square tube to slide onto the hinge block 3 and stay there for a short time, thereby driving the hinge block 3 to rotate, a plurality of anti-slip grooves 12 are provided on the top of the hinge block 3 .

[0023] In some embodiments, in order to reduce the collision between the top 7 and the hinge block 3 when the top 7 descends and deflects, both ends of the top plate 7 are provided with chamfers.

[0024] In some embodiments, in order to facilitate the square tube to slide accurately onto the hinge block 3 when it slides down, guide plates 13 are installed on both sides of the conveying platform 2.

[0025] In some embodiments, in order to facilitate the falling of the square tube on the hinge block 3, two limit columns 14 are installed on the frame 1. The limit columns 14 are arranged in conjunction with the hinge block 3. When the hinge block 3 rotates to a certain angle, it collides with the limit columns 14, thereby allowing the square tube to fall into the frame 1.
